6 Claims.

plaited or folded paper between each sheet of the wet printed copy as the copy is ejected from the machine. Another object is 'to provide a machine or device for this purpose which is simple and inexpensive, yet positive in action, and may be run at sufficient speed to slip-sheet the copies discharged from any of the printing and duplieating machines.

An advantage of this device is that a pack of continuous folded or fluted paper may be repeat- V edly used for the protection of printed sheets to i eliminate what is commonly known as off-set.

Another advantage of this device is that the printed copies are easily removed from the pack after the ink dries. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the following claims.

Reference is had to the accompanying drawing which forms a part of this application.

Fig. 1 is a side elevation of the device attached a mimeograph machine, showing one of the folded furrowed sheets falling over a printed copy. I Fig. 2 is a plan view of the device, showing the folded paper magazine positioned at an angle to 5 the tray.

Fig. 3 is a perspective view of the same, showing one side of the magazine removed to illustrate the position of the pack.

' Similar characters of reference are used to 40 indicate the same parts throughout the several views.

The device consists of a magazine 1 which is I supported upon and positioned at approximately right angles to a copy receiving tray 2. The maglower ends of the side walls 3 are provided with horizontally projecting flanges 6 which extend outwardly from the side walls and rest upon a raised portion 7 of the base of the tray 2. The

p h portion 7 serves as a base for the magazine 1.

A pack of folded or plaited paper 8 is placed in the magazine 1 so that the plaits of the pack extend parallel with the base '7 of the magazine. A fold or two of the pack 8 is first placed in the tray 2 so that the top of the next fold of the pack is caused to fall forward and against the are 11 of the lever 5. One of the flanges 6 is pivotally connected to the portion 7 and the other flange 6 0f the magazine 1 is provided with a bolt 9 which passes through a slot 10 in the base portion 7 The bolt 9 and slot 10 permits the magazine 1 to be adjusted so that it faces at an angle, more or less, to the tray 2. When the magazine is thus positioned at an angle to the. tray 2 the folded or hinged paper 8 will fall into the tray 2 at a greater speed than when the magazine is facing directly towards the tray. The magazine 1 is also set in a reclined backward position on the base 7 sufficient to prevent the pack of folded sheets 8 from toppling forward. a

The lever 5, which is journaled in the upper part of the sides 3 of the magazine, times the fall of the furrowed sheets 8. The lever 5 is provided with a downwardly extending are 11 in the center thereof which normally hangs down in the path of the sheets 8 in their fall from the magazine 1. One end of the lever 5 is provided with a loop 12 through which a reciprocating rod 13 passes. The rod 13 is provided with a hook 14 on the end that passes through the hook or loop 12 and the hook 14 is adapted to swing the lever 5 when the rod is moved forward and the hook 14 engages the loop 12. The other end of rod 13 is pivotally connected to a crank arm 15 which is rigidly attached to the end of the continuous feed shaft 16 of the printing machine. The revolving of the shaft 16 causes a reciprocating movement of the rod. 13 thus actuating the lever 5.

When the lever 5 is partially revolved by the reciprocating arm or rod 13 the are 11 will be raised permitting one fold at a time of the folded sheets 8 to fall from the magazine 1 into the tray 2. The release of one fold at a time of the pack 8 is attained by the forward movementof the rod 13 which permits the hook 14 of the rod 13 to engage and swing the loop 12 of the lever tion. When the lever 5 is in normal position the are 11 will hold the next folded sheet 8 within the magazine until the hook 14 again engages and actuates the loop 12. This method of controlling the folded sheets 8 permits the sheets to fall from the magazine 1 to the tray 2, a fold at a time, until the magazine is exhausted. The release of the sheets 8 are synchronized with the discharge of the printed copies so that a fold of the sheets 8 will be inserted between each printed copy projected from the printing machine. When the arc 11 is moved forward a fold of the plaited pack 8 is permitted to gravitate to the tray 2 of the machine. Each time a fold of the paper fallsinto the tray 2 it has a tendency to pull the next fold of the pack forward and against the are 11 of the lever 5. When the arc 11 is moved to its extreme rear position it engages the upper portion of the pack 8 and pushes the pack back against the rear wall 4 of the magazine 1. The hook 14 is formed on the rod 13 so that it will engage the hook 12 of the lever 5 and swing the are 11 backwards with a given amount of pressure. When this amount of pressure is attained the hook 14 will disengage the hook 12 and permit the are 11 to swing back to a vertical or normal position, as shown in Fig. 3.

The copy receiving tray 2 is provided with two bases, the raised base '7 and an integral lower base 17 which extends forward from the portion or base 7 and rests upon the frame of the mimeograph or similar machine. The forward end of the base 17 is provided with a curved portion that forms a hook 18 for engaging a horizontal brace 19 of the machine to hold the device in operative relation to the machine. The sides of the base 17 are turned up to form guards 20 to receive the folded sheets and the printed copy. The plaited or folded pack 8 may be inclined rearwardly from the tray 2 so that the bulk of the pack will not bear against the are 11 of the lever but lean against the rear wall 4 of the magazine 1. This position of the bulk of the pack relative the arc 11 and the tray 2 permits the fold of the pack 8, adjacent the are 11, to be pulled forward and against the arc 11 by the pull of the last fold released into the tray 2. The amount of pull of the fold in the tray 2 against the fold engaging the are 11 is governed by the adjustment of the magazine 1 on the base 7.

It is apparent that various changes may be made in the size, shape, and arrangement of the various parts of the device without departing from the gist of my invention.

What I claim is:

1. In a slip-sheeting device for printing and duplicating machines provided with a tray; said slip-sheets consisting of a pack of continuous folded paper positioned in operative relation to said tray, means for permitting one fold at a time of said pack to gravitate into said tray, and means for synchronizing the discharge of printed copy from said machine with the gravitation of said folds for inserting one of said copies in the furrow of each of said folds.

2. A device for automatically interposing protective leaves between successively delivered freshly printed sheets or the like, comprising: a table for receiving said sheets as delivered, a leaf pack consisting of a continuous accordion-plaited sheet providing a multiplicity of hingedly connected double leaves, and positively timed means for effecting interleaving of said double leaves between said sheets as the latter are successively delivered to said table.

3. A device for automatically interposing protective leaves between successively delivered freshly printed sheets or the like, comprising: a table for receiving said sheets as delivered, a leaf pack consisting of a continuous plaited sheet providing a multiplicity of hingedly connected vertically disposed leaves successively tending to gravitate upon said table, a detent normally effecting retention of said leaves in a vertical position, and means operated in timed relation with the delivery of said sheets and effecting actuation of said detent to release a leaf upon each sheet after delivery of the latter to said table.

4. A device for automatically interposing protective leaves between successively delivered freshly printed sheets or the like, comprising: a table for receiving said sheets as delivered, a leaf pack consisting of a continuous accordion-plaited sheet providing a multiplicity of hingedly connected double leaves, means for supporting said leaf pack above said table, and positively timed means for effecting interleaving of said double leaves between said sheets as the latter are successively delivered to said table.
